CPC H04N 25/767 (2023.01) [H04N 25/63 (2023.01); H04N 25/633 (2023.01); H04N 25/745 (2023.01)] | 20 Claims |
1. An image sensing device comprising:
a first test block including a plurality of first image sensing pixels structured to convert incident light carrying an image into a first pixel signal indicative of the image, and a first heating element structured to transmit heat to the first image sensing pixels;
a second test block including a plurality of second image sensing pixels that each include a light blocking structure to be shielded from receiving incident light to generate a second pixel signal without being directly exposed to the incident light, and a second heating element structured to transmit heat to the second image sensing pixels; and
a readout block configured to process the first pixel signal output from the first test block and the second pixel signal output from the second test block.
